Re: Code that does page outs

[Eugene Teo <eugene.teo@eugeneteo.net>]

Ah, looks like I need to look at kmem_cache_reap too. 
When shrink_caches() is called, first the slab allocator
is asked to free the pages. If the pages are not entirely
freed, the remaining pages will be freed from other caches.
